What is chronic venous insufficiency? How do you get it?

In brief:
Chronic venous insuf

Chronic venous insufficiency is due to the back flow of blood in the veins usually in the lower extremities.

Back flow is usually protected by valves in the veins that become faulty over time allowing blood to pool. This increases the pressure of blood in the veins and fluid (and a small amount of blood) leaks into the tissues causing swelling, pain, inflammation, and on the skin ulcerations.

In brief:
Heredity

Drs. Bolhack and zimmet have given very nice answers that i agree with.

As far as the cause, there are really two. The major cause is heredity causing venous valves to stop working properly and causing the back flow, high pressure and inflammation that produces skin damage, swelling and ulceration.. The less common cause is post thrombotic resulting from a blood clot that causes valve damage.

In brief:
Vein pooling

Cvi occurs when there is reduced flow or pooling in leg veins, causing leg swelling, inflammation, & ulceration. The most common cause is when the one-way valves don't work well, leading to venous reflux, or back flow, with blood pooling in the veins. This can result from genetic predisposition, pregnancy, injuries or blood clots. See a vein specialist.
